No, I actually am. I am pretty sure I'm comfortable between a disc lock and comprehensive insurance for things that are heavier than a scooter. Thinking about putting a ground anchor in the car port behind my house so I don't have to keep the ninja in the garage.

But beyond column lock and disc lock, does anyone take any other sort of locking measures when parking in the city?

Oh, I think disc lock with shrieky alarm is probably going to be the best suggestion. This person wants to ride his old beemer downtown, but is worried about theft. I tend to think that if he's somewhere that's as public as in front of the cat then the risk of people coming and picking it up is low, but that's not a great answer to the "how do you lock it up" question.
